👉 PGP (Public Key Infrastructure) engineering is the comprehensive design, implementation, and management of a secure digital environment that leverages public key cryptography to enable secure communication, data integrity, and authentication. It involves creating and maintaining a hierarchical structure of digital certificates issued by trusted Certificate Authorities (CAs), which verify the identity of entities and encrypt/decrypt messages. Key components include Certificate Authorities, Registration Authorities, and End Entities, each playing a role in issuing, validating, and managing digital credentials. PGP engineering also encompasses key pair generation, secure key exchange protocols, and robust key management practices to ensure confidentiality, integrity, and non-repudiation in digital communications.
